If you’re so inclined, you can build your own air purifier with laser cut panels or 3d printed panels and use a cheap ikea air filter and standard PC fans. All the parts are readily available, and user repairable. If you pair if with an Apollo AIR-1 you can have home assistant ramp up and down the fans with a PC fan controller based on live readings of PM2.5 in your home. I did this with the help of Claude code. http…

if you're going to IKEA for the filters you might as well buy the whole purifier. it's cheap and it works well

aye, it's ikea and is cheap. this seems like a "i had a ton of parts around + a 3d printer" sorta thing

Looks like a cool project, but the 99.97% HEPA filters are the expensive part. Building yourself only makes sense if you want to choose your own aesthetics or enjoy doing it.

It also makes sense if you're worried that a proprietary filter will be yanked off the market, leaving you with an unusable item. Also, for the money, you cannot get that kind of smart functionality from my research.

Living very close to busy highways is known to generate poor air quality. I recommend anyone in those locations buy an air purifier for their kids' rooms. I bought a couple reasonably priced HEPA purifiers and I change the filters on schedule. Replacement HEPA filters are very cheap. Also watch out for things that we do indoors that can generate bad air quality. I had a friend who bought a VOC meter and noticed very…

what a nice externality example "I recommend anyone in those locations buy an air purifier for their kids' rooms" I drive the car, you buy the purifier.

the purifier is $30 and low maintenance.

buying a new house will have $40k in reltor fees alone, $2k for movers, plus the, you know, hundreds of thousands for the new house. and what if I like my current house, it's in a busy hip area?

or should I launch a multi-year lobbying campaign in the city and/or state and/or national level to have roads moved?

I'm not really sure the thing they were trying to measure was measurable with the study design and level of funding they had. To be fair, the paper is fairly clear on the limitations and much better than the press release.

The study is supposed to measure how clearing up pollution in London improved children's lung function. The decrease in London was meaningful — NO2 fell about 22%. But particulates fell faster in Luton and NO2 in London is still roughly double Luton's. The gap is larger than the decrease.

By 2022 both cohorts get the same results on blow tests. But how does this happen if we believe that the study's dose-response model is true?

Put another way, if the change in London NO2 is so crucial, how come it doesn't matter that the absolute value is still double Luton's?

I really wish the DIY folks would measure the airflow and sound levels on this sort of thing. CADR and decibels are going to vary wildly with fan choice

DIY folks are not a commercial outfit with access to testing equipment.

Having said that, there are reviews of some DIY models reviewing CADR[1], and it's bizarre to complain about testing decibles since Arctic P14 fans, the most commonly recommended fans, are a thouroughly tested product. Running them at around 25% based on lower PM2.5 readings is almost inaudible from experience.

China has 350 million electric two-wheelers, 20 million EVs. China reduced air pollution from transportation by 80% in a decade. Delhi: 442. Lahore: 334. Beijing: 16. These are the levels of PM 2.5, one of the principle measures for air pollution, on November 19. How China cleaned up its air pollution – and what that meant for the climate: https://theconversation.com/how-china-cleaned-up-its-air-pol...

Outdoor pollution ---> Use these for transportation: walk, bicycle, e-scooters, public transit, electric 2 wheeler, EV Indoor pollution ---> Use these for cooking (induction, electric resistance) stove, heatpump waterheater and furnace for HVAC Would also be nice to do: stop using coal, gas power plants. These are usually farther out from cities and probably not the most urgent. (except when Elon Musk or new DCs deci…

So you support nuclear power?

Newsflash, living in a healthy environment is healthy!

Pointless anti-intellectualism. There is a big difference between believing something is true, and demonstrating it is true and measuring the effect. One is a vibe. The other can drive policy.

Found the government consultant!

I support solar. Democratize energy, everyone should have the right to produce and store energy.

1) Plug-in solar and batteries are plug-n-play. This is the first step to teach everyone energy literacy and numeracy.

2) Vertical panels immediately add 3 - 4 hours. Vertical panels have zero real estate cost and no need to build costly and slow transmission infrastructure. Every building in a city can produce energy.

3) EVs to store excess energy during the day and supply power back to the grid later.

1.8 billion vehicles connect 4 billion buildings. Buildings can produce clean energy and EVs can store energy. The lowest hanging fruit is to make sure all new buildings are built to produce, and all new vehicles are EVs. New buildings can be built with vertical panels and rooftop. The easiest thing to do is change building code, thats it. Then, we can deal with the built environment.
